I love it 
A 1990 skyline ! was it a six ? Anyway i bet he was suprised , possible he thought you where driving a 944. i'm still amazed at how many people still call mine a 944 , no matter how many times they see 924 on the car or how many times you tell them.

It had the GT badge on the side and looked stock.I'm not sure how a Skyline is geared but the 931 is hard to beat when it's in 5th on the highway and pushing 13psi. It's just (giggity) sweet !
It's funny,in the last few years there has been a HUGE increase in RHD vehicles that have been imported from (mostly) Japan. Fairladies,Silvias,Landcruisers,MR2's,Skylines and a whole swack of other minivan looking things that I don't even know the names of.I saw one the other day that looked like a half sized 1980's Toyota minivan.According to the badge on the back it's powered by a 1 liter turbo diesel engine.Funky wierd.

Anyone got a pic of one of those things installed? I'm a bit ignorant... I'm not exactly sure how they'd be installed? Like, do you have to remove the exhaust to fit one? I assume they're a little more expensive than a regular screw/valve type... what do they cost? And I guess you need to wire them up somehow, right?

It's a box about the size of a cigarette pack with two wires and about 18" of 1/4" silicone hose attached to a "T" type fitting. The "T" fitting goes anywhere on the wastegate control line,but before the wastegate.The control box itself has two dials on it.One controls the low setting then when you flick the switch on the dash it opens a solenoid that allows an extra amount of air to bleed off creating your high boost setting.It can be switched from low to high on the fly even when your already "on the boost". You should be able to get one relatively cheap in Aus because they're made there !
Look here- http://www.dsmparts.com/customer/product.php?productid=7
This isn't quite what they claim,the dual stage is supposed to have two dials on it not just one,but everything else is the same.

Keno,
I thought I read that you had to modify yours a bit, to allow more air to flow through? Or am I smoking something? lol.
I would definately love a dual stage, but it just seems like they are way over priced. If they were about 100$ I would look into it. $200 for a solenoid and some needle valves seems a bit high.

Yeah I almost forgot I did have to drill the opening to a slightly larger diameter.If anyone buys one let me know and i'll measure mine so you can do it to.

Out of 135,000+ posts on this board I can only remember seeing one dyno chart posted, the one I posted. There may be others but the number is so small that you have to assume that no one here has ever had one done or if they have they're too embarassed to post it.
Rather than waste time talking about driveline loss put it on the rollers and for $50 you have the answer. |
er, I know I'm reading an old post, but I posted my dyno too!
btw, quoted transmission loss for the 924/944 series according to the guys at Weltmeister (running their Dyno Dynamics Dyno) was 18%. my speculation was that this figure could be higher if the car wasn't in tip top condition?

As I understand it, that's right... drivetrain wear (and other factors) will have some effect on the loss of power over the drivetrain. Problem is, as far as I understand it, it's all but impossible to know exactly what the loss is without pulling the engine and putting it on an engine dyno.
However, sequential and others, who have some experience with this, are reasonably sure it'd be somewhere between 15% and 20%. Which also fits with the number you were quoted.
So, I guess the main question is, would you prefer to quote your flywheel horsepower at the upper limit (say, factor a 20% loss) or at the lower limit (with only a 15% loss, for example)?
With a 15% to 20% loss, mine is guesstimated at about 173 to 180-odd horsepower at the flywheel. That feels about right, near-enough stock horsepower... maybe a tad more

great, that means my 121.4 translates to 123.4 woo hoo.... (and a load of decimal points, I didn't just add 2!)
not exactly an exact science, but I believe that the 18% is a figure quoted by porsche, not a guesstimate...

The dyno should be able to measure the drivetrain loss, just have the operator do a coast down drag test for the exact figures on their rollers..
18% is reasonable , he might measure closer to 15% ..
Also less not get carried away with the factory numbers because it is a min average , done to make sure all the cars will see this rating , on the avg the engines tend to be a bit more , a few a bit less....
121 or 123 does'nt matter it is still not enough
